TW2
. One 2-wire bus cable must be dedicated to one of
the two terminal blocks and not shared across the two
blocks
•
Draw both wires (2x ‘figure 8’ cable) from the wall cavity
and feed them through the large slot in the backing plate
•
Connect the 2-wire bus cable from the heater to the NC-6
TW1
and
TW2
terminals in the same block
•
Repeat the above for the second 2-wire bus cable for first
NT-1 and insert into the second terminal block
3. Mounting the backing plate
•
Position the backing plate on the wall and mark the two
mounting positions on the wall
•
Insert wall plugs (field supplied) in the marked positions to
suit the Ø3.5mm (6 gauge) screws supplied with the NC-6
•
Secure backing plate to the wall, push back excess 2-wire

Installation
1. Backing Plate Removal
•
Unclip the backing plate from the user interface by
disengaging the top and bottom clip. Separate once this is
achieved
2. Connecting 2-wire bus cable
•
Run cable to the position of all temperature sensors as
shown in Diagram 2, p.7
•
There should be enough 2-wire bus cable at each NT-1,
excluding the last, to enable daisy chain connection
3. Connection of bus cables to NT-1 backing plate
•
There are two terminal blocks on the backing plate of the
NT-1. One 2-wire bus cable must be dedicated to one of
